We study non-perturbative quantum aspects of $T\bar{T}$-deformation of a free$O(N)$ vector model by employing the large $N$ limit. It is shown that boundstates of the original field appear and inevitably become negative-norm states.In particular, the bound states can be regarded as the states of the conformalmode in a gravitational theory, where the Liouville action is induced with thecoefficient proportional to the minus of central charge. To make the theorypositive-definite, some modification is required so as to preservediffeomorphism invariance due to the Faddeev-Popov ghosts with a negativecentral charge.
